You don’t need to convert a .mod file if you have Vegas Movie Studio HD Platinum 10. It reads them. When importing your media, under the ‘Files of type’ drop-down, make sure you scroll to the top and select ‘all files’. Then you’ll see the .mod file. Select it and add. If your video was filmed in 16:9 widescreen format you’ll need to alter its pixel aspect ratio so that it displays correctly. To do this, right-click on the file’s icon in the media window, go to Properties then Pixel aspect ratio, and select the appropriate ratio for your desired output (e.g. if you’re going to create a widescreen DVD for a PAL audience Europe/UK, select PAL DV Widescreen).
